YS-Tech are the creators of the Tip Magnetic Drive Fan, and the Coolsonic CS1672A makes use of an all-black version.

It's hard not to be a little impressed each time a TMD fan spins up creating
its distinctive 'whirling' sound. The Coolsonic CS1672A comes to us
from Kai-Way Technology, and packs a 75mm all-black TMD fan which gives it a nice
appearance, and plenty of cooling potential.

Based on the copper skive process, the CS1672A comes bearing
many little razor sharp copper fins which should make it an excellent heatsink.
We have yet to see a skive heatsink which didn't perform towards the upper end
of the spectrum (mind you, they aren't quite at performance cooling levels,
yet). The Coolsonic CS1672A looks to be no different.

The company which makes this heatsink is called Kai-Way Technology. Kai-Way
have been in business since 2001, and are currently based in Taipei Taiwan. While we haven't seen much North American distribution of Kai-Way's "Coolsonic" branded heatsinks, they
should be readily available in Asia.

If you
are wondering about these Skived Copper fins
we speak of, the explanation is pretty simple.
The manufacturing process is analogous to a chisel cutting into a piece of wood at a very
shallow angle. The difference is that the cuts are much more controlled and result
in straight bits of metal (the fins) standing upright.

If you were to look very closely at one of the
resulting fins you would see one bumpy
side which has been created by the shearing
forces as the copper was drawn up. From a standpoint of crystalline structures this is
kind of cool, but insofar as heatsink performance is concerned it is merely academic.
Next, we look at the heatsink from all sides.
